While I amend the cancelled sales invoice there is an error message popping up saying change the naming series as per GST rules which we cannot change (naming series)
Here is the screenshot of my naming series list for sales invoice the highlighted is the one which i am using for current fiscal year which is less than 16 characters.
If you are operating in a bureaucratically regulated environment such as India, having the revision numbers on a Sales Invoice just invites a lot of trouble. Here’s how you can make a Sales Invoice that needs correction into the corrected invoice but with the same number as the original.
Plus you can adopt a simpler naming series that does not add up to 16 characters. Like say 10, including the series, so that you don’t have to worry about the revisions.
